- Patented Jam; 19, 1932 T S PA ENT OFFICE ALFRED KOOEEO'USE, OBDETROIT, MICHIGAN, ASSIGNOR T0 PACKARD HOTORCAR GQANY, OF DETROIT,MICHIGAN, A CORPORATION OF MICHIGAN J arncnanrsm This invention relatesto motor vehicles and more particularly to brakes thereof.

Heretofore various means have been employed in eiiorts tending towardthe elimination of squeak or tone vibrations encountered in the use ofmotor vehicle brakes of the various types now employed. Such efiortshave been directed rincipally to modifying the brake shoes and t e brakebands or linings and the results obtained have not proved entirelysatisfactory.

In brake structures comprising a brake support late having brake shoesanchored thereon or cooperation with a brake drum, there is set up, whenthe brakes are applied,

' tone vibrations in both the brake support plate and brake drumresulting in a disagreeable s ueak. These tone vibrations are caused ythe spasmodic co-action between the shoes and the brake drum. Thissudden and irregular gripping action between the shoes and the drum isintensified under va- 1 rious conditionsresulting in the buildingup oftone vibrations of considerable amplitude.

It is the aim of the resent invention to re duce or eliminate t ese tonevibrations or from the following description taken in consqueaks.

An object .of the invention is to provlde a mountingfor the brakesupport plate which will reduce or eliminate the squeak common to brakesnow in general use.

Another object of the invention is to provide a brake support plateconnected by a resilient means to an axle of a motor vehicle.

I Another object of the invention is to provide a brake support platecushioned upon a stationary axle of a motor vehicle in a mannor toreduce or eliminate vibration that would otherwise be transmittedthereto.

Another object of the invention is to provide a brake su port plateconnected by a 4 plurality of resilient members to a stationary axle soas to absorb vibrations which would otherwise produce disagreeablenoises.

A further object of the invention is to provide a brake support platewith means for dampenin the tone vibrations in the brake ls)up ort p ateand the associated parts of the ra e. a

A further object of the invention is to provide a brake support platemounted upon a stationary axle and adapted to rotate thereupon andhaving an interconnected means for restricting the rotation of the plateupon the axle, the said interconnected means being of plate.

Still a further object of the invention is to provide ,a brake supportplate and means for mounting the same, havingthe advantages of apositive check or damping action on tone vibrations, is highly eflicientin operation and yet of marked simplicity as a whole and in respect toeach of its component parts and their assembly. I

. Other objects of the invention will appear nection with the drawinwhich form a part of this specification, an in which:

Figure 1 is an enlarged plan view of a brake illustrating the rear axleshaft bearing sleeve mounted on a rear axle and equipped with theinvention, and

F1gure 2 is a vertical sectional view of a portion of a rear axle andbrake illustrating the invention as applied.

Referring by numerals to the drawings 10 represents a portion of therear axle of a motorvehicle, having mounted thereupon a bearing 11secured in osition by a check nut .12 and a retainer 13, t e retainerhaving the usual retainer washer and washer nut as in dicated at 14 anda radial flange 15. A bearing sleeve 16 is fitted over the bearing 11and retainer 13 and provided with the usual dust washer and dust washerretainer indicated at 17. The bearing sleeve 16-abuts the flange 15 uponthe retainer 13 and is provided with a plurality of threaded aperturesre 'stering with apertures in the flange 15 for t e reception of bolts18, by means of which the sleeve 16 is secured to an axle housing 19with the flange 15 of the retainer clamped 'therebetween.

The bearing sleeve 16-is provided with a support plate 26 comprises a.plate having a peripheral flange 27 and a central opening 28, theopening 28 receiving the reduced end portion 20 of the bearing sleeve16. The plate is mounted to rotate in the circumferentialgroove 21formed by the reduced end portion, the radialshoulder on the bearingsleeve and the radial flange on the retainer.

The plate 26 is provided with a plurality of apertures arranged adjacentthe central opening 28 in spaced relation thereto and to each other.These apertures receive, stud bolts 29 each having a radial flange 30and a nut '31 by means of which the bolts are clamped to the plate 26.The bolts 29 extend normal from the plate 26 and engage the innersleeves 25, in the bushings 24, the radial flan s 30 on theboltsabutting the bushings. nthe structure shown, the plate 26 is mounted torevolve on the sleeve 16 and is restrained in its movement by theresilient bushings 24. The support plate 26 is provided with a stud 32upon which are anchored suitable brake shoes 33 having linings 34adapted to engage a brake drum 35 carried by a wheel hub 36, the hubbeing suitably secured u on the axle and provided with a hub cap 3 andhaving mounted thereu on a wheel 38 only a portion of which is s own.

While I have herein described in some detail specific embodiments of myinvention, which I deem to be new and advantageous and may specificallyclaim, I do not desire it to be understood that m invention is limitedto the exact details of t e construction, as it will be apparent thatchan s may be made therein without departing rom the spirit or scofie ofmy invention.

aving thus described the invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a motor vehicle, the combination of a stationary axle, a wheelmounted for rotation relative thereto, a brake drum carried by saidwheel, a brake support plate, brake shoes on said plate for cooperationwith said drum, means connecting the plate to the axle for relativerotation thereto and a compression member restraining the rotarymovement of the plate in either direction from a position in which thebrake is released.

2. In a motor vehicle, the combination of a stationary axle, a wheelmounted for rota-' 'tion relative thereto, a brake drum carried by saidwheel, a brake support plate, brake shoes on said plate for cooperationwith said drum, brake applying connections for said shoes, meanssupporting the plate upon the axle for relative rotation and rubbercompression members restraining the rotation of said plate in eitherdirection.

3. In a motor vehicle, the combination with an axle having a bearing anda bearing retainer, of a sleeve for said bearing having a plurality ofapertures, resilient members in said apertures, a brake support plateand means on said plate for attachment to saidresilient members.

4. In a motor vehicle, the combination with an axle having a bearingthereon, a retainer for said bearing, of a bearing sleeve having aplurality of radial lobes provided with apertures, resilient membersmounted in the apertures, a brake support plate and means upon iaidplate for engaging said resilient memers.

5. In a motor vehicle, in combination with an axle having a bearingthereon and a retainer for the bearing, of a bearing sleeve havingradial lobes provided with apertures parallel to the axis of the axle,resilient memers in the apertures, a brake support plate and studs uponsaid support plate engaging said members.

6. In a motor vehicle, a brake mechanism comprising a brake supportplate, a wheel I mounted to rotate relative to the brake support plate,a brake drum carried by said wheel, brake shoes upon the support platefor cooperation with said brake drum, said brake support plate mountedfor rotation and rubber compression. members restricting the rotation ofthe brake support plate in either direction, whereb spasmodic co-actionbetween" the brake s oes and the brake drum is prevented.

7 In a motor vehicle, a brake mechanism comprising a brake support late,a wheel mounted for rotation relative thereto, a brake drum carried bysaid wheel, brake shoes anchored upon said support plate, means foractuating the brake shoes for cooperation with the brake drum, meansmounting the brake support plate for rotation and rubber compress onmembers for restricting the rotation of the plate in either direction,whereby sudden and irregular co-action between the brake shoes and thebrake drum is prevented.

8. In a motor vehicle, a brake mechanism comprising a brake supportplate mounted for rotation, a wheel mounted for rotation relativethereto, a brake drum carried by said wheel, brakes mounted on the brakesupport plate for cooperation with said drum and compression members forrestrictin the rotation of the brake support plate in either direction,whereby vibration in brake support late, the'brakes and the drum isprevente said compression members being formed of rubber.
